Sorry for the loss.
I searched and guess that they were not able to tolerate stress of changed water from LFS to your aquarium and this may be the cause:
"Otocinclus Catfish care is relatively easy. But while care should be easy and straight foreword, keeping Otocinclus Catfish can be tricky because they a delicate freshwater aquarium fish. Otto Cats often die shortly after being added to an aquarium, even after appearing to be healthy, active and feeding well during the first few days. That said, some can live over one year and grow in size…under the right conditions and with a little luck."
